## Probable cause

The student pilot’s failure to maintain control of the airplane during the crosswind landing, which resulted in the airplane drifting off the left side of the runway and into trees.

## Analysis

The student pilot was conducting a solo flight when he was unable to keep the airplane aligned with the runway centerline due to a right crosswind. Witnesses reported that the airplane veered left of the runway and struck trees before it came to rest in a grass area. After the accident, the student pilot stated that he had difficulty with the right crosswind and believed the airplane had an aileron issue. The student pilot stated that the airplane’s left wing collided with the trees with the engine at full power. The airplane’s left wing and forward fuselage were substantially damaged during the accident. Examination of the airplane revealed no preimpact mechanical anomalies or failures that would have prevented its normal operation. Flight control continuity for the ailerons, elevator, and rudder was confirmed. It is likely the student pilot did not maintain control of the airplane during the crosswind landing, which resulted in the airplane drifting off the left side of the runway and into trees.
